How do I fix no sound in Microsoft Flight Simulator?
No sound in Microsoft Flight Simulator is usually caused by the wrong Windows or Xbox output device, muted application volume, a disconnected USB or Bluetooth headset, or an in-sim audio setting. Restart the simulator after selecting the correct device, then check the volume mixer, MSFS audio sliders, add-ons and audio drivers.
What does the silence affect?
The pattern of missing sound usually identifies the faulty layer before you change anything. Check menu sounds, a default aircraft’s engine, cockpit warnings and ATC separately.
| Symptom | Likely cause | First check |
|---|---|---|
| Everything in MSFS is silent | Wrong output, muted application or zero master volume | Windows or Xbox output and the MSFS master slider |
| ATC is silent but the aircraft is audible | Communications output, voice slider or text-to-speech setting | ATC audio and communications device |
| Only one aircraft is silent | Aircraft package or sound-mod conflict | Test a stock aircraft, then disable add-ons |
| Sound vanished after changing headset or entering VR | MSFS retained the old audio endpoint | Select the device again and restart the simulator |
| Sound stops while MSFS is in the background | Background-audio setting | Enable sound when the application loses focus |
How do I restore all sound on a Windows PC?
The fastest PC fix is to select one output device in Windows and MSFS, unmute the simulator in Volume Mixer, and relaunch it.
- Confirm that Windows itself has sound. Play audio in another application. If that is silent too, fix the Windows output device, headset, speakers or amplifier before changing MSFS.
- Select the intended Windows output. Check the speaker control on the taskbar. HDMI monitors, VR headsets, gamepads, USB interfaces and Bluetooth devices can become the selected output without being the speakers you are using.
- Inspect Volume Mixer while MSFS is running. Make sure Microsoft Flight Simulator is not muted and that its application volume is above zero. Windows can also remember a different output device for one application, so assign MSFS to the same device selected for the system.
- Open the simulator’s Sound or Audio settings. Raise the master volume and the relevant aircraft, engine, cockpit, warning, voice and UI sliders. Labels differ between Microsoft Flight Simulator 2020 and 2024. If separate main and communications outputs are offered, point both at the same device while diagnosing the fault.
- Quit and relaunch MSFS completely. The simulator may retain the device available at launch. Simply changing the Windows output after MSFS has started does not always move an existing audio session.
- Test a default aircraft in a simple flight. This separates a system-wide fault from a problem affecting one downloaded aircraft or sound package.
A physical headset control can override every software setting. Check inline mute switches, USB-interface gain controls and game/chat balance wheels as well as Windows volume.
Why can I hear the aircraft but not ATC?
Silent ATC with normal aircraft audio is usually a separate communications-output, voice-volume or text-to-speech problem.
- Raise the ATC, voice or communications slider in the simulator’s audio settings.
- Set the communications output to the same working device as the main simulator output.
- If ATC text appears without speech, check that text-to-speech is not disabled. Online speech depends on online services; an installed offline voice option can be used where the simulator offers one.
- If there are no messages at all, confirm that the aircraft has electrical power and that its radio is tuned for the service being used.
MSFS ATC is generated by the simulator rather than taken from real-world radio frequencies. Our explanation of how simulated ATC differs from live airport radio also covers the separate device and application-volume checks needed for external radio audio.
Why is only one aircraft silent?
If stock aircraft have sound but one aircraft does not, the affected aircraft package or an overriding sound mod is the likely cause.
- Load a default aircraft at the same airport and confirm that its engine, switches and warnings are audible.
- Remove sound-related add-ons temporarily. On PC, use our guide to locate the active Community folder for each installation type, then move suspect packages outside it before restarting MSFS.
- Update or reinstall the affected aircraft package. For content managed inside the simulator, use its content-management controls rather than looking for it in the Community folder.
- Check the aircraft state. A cold-and-dark aircraft will not produce engine or powered warning sounds until the relevant systems are running.
A mistake we see constantly is removing an add-on from the wrong Community folder. Multiple MSFS installations or platform versions can leave more than one folder on the same PC.
Why does sound disappear after changing headphones or using VR?
Microsoft Flight Simulator may continue sending audio to the device that was active when it launched, even after Windows switches to another output.
- Connect and select the headset or VR audio device before starting MSFS.
- Use the same device for Windows output, MSFS main audio and MSFS communications audio.
- After unplugging a device, close and reopen the simulator rather than relying on live switching.
- For Bluetooth headsets, check whether Windows switched between the stereo playback profile and the lower-quality communications profile when the microphone activated.
- Temporarily disable spatial audio and enhancement processing to rule out a driver or format conflict.
How do I fix no sound on Xbox?
On Xbox, fully quitting the simulator and correcting the console’s HDMI or headset output resolves most complete-audio failures.
- Quit MSFS from the dashboard. Do not resume the suspended session through Quick Resume.
- Check the console audio destination. Confirm that sound is being sent to the television, receiver or headset you are actually using.
- Check headset mixing. A game/chat balance set fully towards chat can make the simulator appear muted.
- Restart the audio chain. Reconnect the headset or HDMI cable, then restart the console and any receiver or television.
- Test another game. If that is silent as well, the fault is in the console, display, receiver or headset configuration rather than MSFS.
When should I repair or reinstall Microsoft Flight Simulator?
Repairing game files should come after output, mixer, in-sim and add-on checks; a complete reinstall is the last resort.
- Update or reinstall the Windows audio driver if several applications misbehave with the same device.
- Close audio utilities that may have exclusive control of an external interface, then test with ordinary system speakers.
- Use the platform’s file-verification or repair function if default aircraft remain silent with an empty Community folder.
- Avoid Reset or a complete uninstall until simpler checks fail, because either can require large content packages to be downloaded again without fixing an operating-system routing problem.
